- Abstract:
- Based on the relevant statistical data of ten prefecture-level cites of Shaanxi Province from 2013 to 2017, we used STIRPAT model as a theoretical analysis tool to analyze the main factors affecting air quality in Shaanxi Province. The results show that the relationship between economic development and environmental quality in Shaanxi Province was still in the initial stage of the inverted U-shaped curve of environmental Kuznets from 2013 to 2017, the more the economy develops, the worse the air quality; the air qualities of ten cities in Shaanxi had been improved after implementation of Environmental Air Quality Standard(GB3095—2012)from 2013 to 2017; AQI value was on the rise, PM2.5 value, PM10 value, atmospheric SO2 content, CO content showed a downward trend, but the contents of CO2 and O3 in the atmosphere were still on the rise; the air qualities in northern and southern Shaanxi were higher than that in middle Shaanxi; in the middle stage of urbanization development at present, population, wealth, technology and transportation are the most important factors affecting the air quality in Shaanxi. In order to improve the air quality of Shaanxi Province, it is necessary to control the population density of the city reasonably, adjust industrial structure driven by scientific and technological innovation, reduce the energy consumption per unit GDP recently, continually implement the traffic restriction policy, and develop new energy public transport should. In the long run, we soil and water conservation measures, such as planning and using urban land rationally, optimizing the structure of green forest, increasing the green area, and reasonably using environmental protection funds by using the leverage of financial expenditure, should be strengthened.
